SHEET-METAL BARREL.

Specification of Letters Patent.

Patented Dee. 15, 1914.

Application filed November '21: 1908. Serial No. 463.819.

the same, reference being bad to the aceompany ng drawings, and to thefigures ot' reference marked thereon, wlneh liorni a part of thisspecification.

My invention relates to metallic receptacles, and particularly tosheetanetal barrels of the class having spaced erinips or ribs ellicientand reliable means for obtaining the proper strengthening effect againstexternal compressing forces, with the result. that my barrel orrereptarle possesses the necessary strength and rigidity withoutobstruction to the interior of the barrel or withoutlessening thecapacity thereof.

Further objects of the invention. as well as the construction andarrangement of the phrts thereof. are fully described in the fol lowingspecification. and a' preferred embodiment thereof illustrated in theaceonr pan ving drawings. in \\'l]l('ll,

Figure l is a side ele\ation of a barrel embodying my invention. withportions of the same broken away. Fig. 2 is an end viewdlrereot with aportion in section on the line .11 r in Fig. 1. Fig. I: is an enlargedelevation of a. portion of the barrel. with the part A ll thereof invertical sertion. as on the. line :1 1:1 in Fig. "l, and the part Atherei'if in vertiral sertiou, as on the line 3/ y in Fig. and Fig. 4.is an enlarged portion of one end of the barrel with the head removet'l.

Referring to the drawings. 5 designates the body of the barrel. and t Gthe opposing heads thereof. The body 5 is preferably formed from acylindrical sheet-metal blank. which provided with the inwardly proecting long'itudinallr-extending erimps' or furrows 7. at suitablyspaced distances thrrearound. whirh serve both to strengthen the bodyagainst external compressing stresses and .to nnpart the desired bilgeformation thereto. which latter is accom-' plished by graduallydeepening the-crimps from the. center toward the ends thereof toirimortionately increase the amount of metal taken up thereby. 1 wish itLinden. stood, however. that. I do not wish to restrict my inri-ut-ion'to use in connection with any pariirular shape or formation ofrei-optaele. whether of bilge form or otherwise. or to a ny particularmanner of forming: the same.

'ln the base of each of the crimps or furrows 7 is disposed areinforcing rod or heavy wire, which is firmly held therein by drawingthe outer opposing edges of the crimp together so that they abut, or substautially abut, as shown at 9, Figs. 2 and l. The elosing of the mouthsof the crinips also gives one side of the package the appearanee of asubstantially plain-or unintorrupted surface. Inorder to prevent alongitudinal movement of the rods within the crinips, their ends areterminated short of the ends of the erinips, as shown in Fig. 23. andthe ends of the erimps bent laterally or radially and flattened againstthe inner end portions of the body, as shown at 10, thus Closing theends of the crimpsover the rod ends and forming internal shoulders 11upon which the heads (3. (i may seat. Hy securing the rods 8 within thecrimps in this manner it is evident that the barrel body is made veryrigid in its construction and is capable of resisting very greatexternal fol-res: and also that: the bending of the crimp ends closelyover the rod ends and radially flattening them against the reeepiaele.body absolutely secures the rods ainst longitudinal moveuwnts within therrnnps. reinforces the body chime and forms liriu, rigid seats for thereceptacle heads.

in the present instance the body 5 is encircled by a plurality of hoops12, which are riveted or secured thereto in any other suitablemanner,,and prevent an expansion of the body or an opening of the crimpsfrom their closely compressed state, as shown.

The heads 6 are shown as being stamped from sheet-metal and have theirmajor portions depressed to adapt them to fit snugly within the endportions or chimes of the bar re]. and seat on the shoulders 11 formedat the end portions of the crimps. The chime at each end of the body 5has its edge preferably rolled outwardly to torn; a hoohcd edge withwhich the marginal edge of the respective head (i may engage, said edgeof the head being rolled over the chime and interlocking with the edgethereof, as shown at 13, Fig. l, and the whole then closely compressedto form a firm joint. To prevent an opening of the joint thus formed theend of the barrel is encircled by a hoop or hand 14, which is secured inposition by rivets 15, or the like, passing through it, the chime andoutwardly projecting portion of the head. It will be understood, ofcourse, that the heads of a barrel are not intended. to be taken offafter once being placed thereon, as the barrel is filled and thecontents withdrawn therefrom through the bung-hole 16.

I desire it to be understood that my insuch limitations are specified inthe claim.

Having thus described my invention, what I claim as new and desire tosecure by Let ters Patent, is,

A bilged metallic receptacle having a pinrality of inwardly projectingcrimps formed longitudinally thereof a reinforcing rod dis posed Withineach crimp and bowed to conform to the bilge of the receptacle with themouths of the crimps drawn closely together around the rods to retainthem therein and to provide the receptacle with. a. substantiallyuninterrupted circumferential surface, said rods having their endsstanding inward greater distance from the receptacle wall than thecentral portions thereof and terminating short of the respective ends ofthe receptacle, and the crimp ends being bent closely over the rod endsand fiat against the receptacle body whereby to secure the rods in placeand to cooperate with the lflfiitllli'lr ing ends thereof to form firmseats for the receptacle heads, substantially as described.

In testimony whereof I have hereunto signed my name to thisspecification in the presence of two subscribing witnesses.
